ROTARY-ENGINE GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 627,782, dated June 27,1899. Application filed July 9,1898. Serial No. 685.-5 9- on model.)

Be it known that I, Gnonen O. PYLE, of In dianapolis, county of Marion,and State of Indiana, have invented a certain new and usefulRotary-Engine Governor; and I do hereby declare that the following isafull, clear, and exact description thereof; reference being had to theaccompanying drawings, in which like numerals refer to like parts.

My present invention relates to agoverning inlet will be modifiedautomatically, and thereby the speed of the engine controlled.

While this invention is adapted for use in connection .with varioustypes of rotary engines, I here show it-connected with one sub;stantially similar to the rotary engine set forth in a former patent ofmine, No. 550,56 1,' dated November 26, 18 95. p

The full natureof thisinvention will be understood from the accompanyingdrawings and the following description and claims.

In the drawings, Figure I' is an elevation of a rotary engine, withparts broken away ernor in place. Fig. II is a section on the line A Aof Fig. I. Fig. III is a section on the .line B B of Fig. I, parts beingbroken away.

By referring to my former patent above mentioned the generalnature ofthe rotary engine herein illustrated can be learned.

1 is ashaft having bearings in the casing 2 and upon which the hub 4 ofthe turbine wheel 5 is rigidly secured. 3 are the buckets, and 6 thecover. 7 is-an annular steam-chamberin the casing. S is the steam-inletport leading to the antechamber 9. The foregoing constitutes no part ofthis present invention.

10 is a cylinder secured to the casing, with its chamber in line withthe passage-way 9 or a steam-inlet. A valve or piston 11 operatesthrough said cylinder, and its movement is limited by the screw 12,whose end enters the slot 13 in the piston 11. When the piston 11 ismoved inward to the left, it reduces and finally closes the steam-inlet.The piston 11 is actuated by the lever 14, pivoted intermediate its endson the arm 15 from the cylinder 10. There are two inlets oppositelylocated,

as seen in Fig. I, and hence there are two pistons 11 and levers 14. Thesaid levers 14. are actuated by the arms 16, that are secured to theplate 17 When said plate 17 is moved to the right, the inner end of thelever 14 is likeis forced to the right, it consequently forces the plate17 and the arm 16 in the same dimotion. the wheel by the springs 20, oneof whose ends rests on said collar and the other on' a seat 21, formedon the wheel. Its tension is regulated by aset-screw 22. The arms 16 areheld down. in place by a spring 23, which'at one end is bolted to thecover 6 and at the other end rests on said lever 16.

The mechanism in the governing device heretofore described is caused tooperate by the weighted bell-crank levers 24:. V (Seen in Fig. III.) Oneendof said bell-crank lever is weighted by the weight 25. Its centralportion is pivoted at 26 in a slot in the plate 27, that is bolted tothe wall 5 of the wheel. The other end 28 of the bell-crank leverengages the collar 19. As the speed of the wheel increases the weight 25is moved away from the wheel by centrifugal force, and when it is somoved the bell-crank lever 24 by its end 28 slides the collar 19, andtherefore the arm 16, laterally to the right, whereupon said arm forcesthe plunger in toward the inlet-port.

The collar 19 is held inward toward Obviously the more rapidly saidwheel is rorated greater will be the action of the parts of thegoverning device, resulting in a greater reduction of the inlet-portnntilit would finally be closed.

mounted adjacent to said rotary collar carrywheel and slotted, and theweighted lever 24 ing an arm pivoted to the valve-actuating lepivoted tosaid plate, all combined substanver, and a spring pressing against said'arm' tially as set forth. to hold it toward the wheel.
